ROTATABLE OPEN-BOOK REST.

Specification of Letters Patent. Patented J 11119 16, 1914.

Application filed April 23, 1913. Serial No. 762,977.

To all whom it may concern:

Be it known that I, WVILLIAM J. WALSH, a subject of the King of Great Britain, and resident of Hamilton, in the county of entworth and Province of Ontario, Canada, have invented new and useful Improvements in Rotatable Open-Book Rests, of which the following is a specification.

See my United States Patents Nos. 1,017,120, and 1,017,121, dated February 12th 1912.

My invention relates to improvements in open book rests adapted to be adjusted to various positions on a table or desk.

The objects of my invention are first, to provide an open book rest secured to a table or desk, and adapted to be brought to various positions thereon, second, to provide means whereby the book rest may be secured to either end part or side of the table, and brought to position thereon, third, to provide horizontal means for supporting actelephone receiving instrument, and for holding said instrument on the support; fourth, to provide means in the book rest adapted to allow electric current to give light to the book, when the same is in readable position, and to break the electric current when the book rest is adjusted to an out of the way position; and fifth; to provide means on the book rest to prevent the same from being tilted sidewise too far. I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a front elevation of the open book rest, the inclined supporting arm of which is broken away in order to show the adjustable supporting mechanism attached to a table, desk or Wall together with the telephone supporting and retaining mechanism. Fig. 2 is a side elevation of the same, showing the vertical supporting shaft broken. Fig. 3 is a front sectional elevation of the casing of the device and means on the book rest arm adapted to break the electric contact or current. Fig. 4: is a plan of a portion of the horizontal disk, or plate, showing two openings through the same for a strap. Fig. 5 is an enlarged sectional elevation of the detached insulating block, showing vertical holes therethrough.

Similar characters of reference refer to similar parts throughout the several views.

In the drawing, A, is a horizontal casing, and 2, is a shaft downwardly extending therefrom, and thereof.

B, is a reversible supporting bracket, having upper and lower sockets in vertical alinement one with the other and a distance apart, and is screwed to a table or desk C. Both said sockets are screw threaded a distance in from the outer ends thereof adapted to receive a threaded plug 4:, and the lower end of the vertical shank 5, of the horizontal arm 6, is adapted to rest on the end of the plug and to swing or rotate in the sockets 3, of the bracket B. Should convenience require the reversing of the bracket B, to another, or opposite part of the table, then the same plug may be screwed in the opposite socket, that is, when the bracket is reversed. The opposite end of the arm 6 is rigidly screwed into the side of a boss, or circular head 8, and the vertical shaft 2 passes through. said head and is rotatable therein.

9, is a horizontal arm having a hub 10, which is loosely connected to the shaft 2, and rests on the boss 8, to allow said arm 9 to be adjusted and there fastened by means of the set screw 12. The opposite end part of the arm 9 supports a horizontal disk 13, which is recessed on the top to support a telephone receiving instrument 1 1, thereon, and to retain the instrument in position, a flexible strap 15 extends through openings 0. in the disk, and the ends of the strap are secured together on the underside of the disk by means of a buckle e. The base part 16, of the instrument is adapted to be easily slid under the upper portion of the strap and there retained, without any other fastening, and the instrument is easily withdrawn therefrom, when required.

17 is the open book rest arm, the end parts 18 of which horizontally extend in opposite directions in the casing A, and swing therein, on the fulcrum pin 19, from an inclined position as in Fig. 2, and upward to a vertical position in a similar manner as in my United States Patent No. 1017121, referred to.

20, is the open book rest on the arm 17, and 21 is the stop thereon, to-hold the book when the arm is swung to vertical, or nonreadable position, and 22 is the vertical rear forming an integral part wall on the casing to receive the face of the in the casing A, and a plate 24 is secured therein at one end thereof, and a resilient contact plate 25 secured at the opposite end thereof by means of suitable screws 26, the spring or resilient end part of the plate'25, is underneath the plate 24, and contacts therewith by its inherent resiliency.

28, and 29, are electric wires, one of which contacts with the plate 24, and the other wire with the plate 25, said wires are held by their respective screws 26, one wire extends to the source of power and the other wire to an electric light.

The arm 17 has a lip 30, on which is a rubber sleeve 31 to contact in a noiseless manner with the casing.

32 is a screw through the lip 30 to contact with the plate 25 and press the same downward to disconnect said plate from the plate 24, to break the electric current, and

extinguish the light.

The electric wires referred tomay enter the casing A, and the block 23, at convenient and adaptable places.

The enlarged insulating block in Fig. 5, of the drawing shows holes 35, to receive bolts or screws to fasten the block to the casing, and holes 36 to receive screws 26 to fasten the plates 24 and 25 thereto, together with the electric wires 28 and 29 respectively. The plate 24 is secured on the arm 17, from tilting too far in opposite 1 directions.

hat I claim as my invention and desire to secure by Letters Patent, is

In an open book rest, a casing, a shaft downwardly extending therefrom, a horizonta-l shaft having a downwardly extendin g shank at one end and a head at the opposite end thereof, said shaft extending through the head, a reversible bracket having sockets one above the other to receive the shank, the outer end parts of the sockets screw threaded, a removable plug screwed. in the lower socket to allow the end of the shank to rest thereon, and the same plug to screw in the other socket and for the same purpose, upon the reversing of the bracket.
